deemed to constitute an assignment or an attempt to assign any asset, contract,
claim, right or other agreement to which Seller is a party if the attempted
assignment thereof without the consent of the other party to such asset,

contravention thereof or affect in any way adversely the rights of Seller
thereunder.

        Except as otherwise set forth in the Seller Disclosure Schedule,
attached hereto as Schedule IV, the following representations and warranties are
made by Seller as set forth below:



                                       9


        4.1 Organization. Seller is a corporation duly organized and validly
existing under the laws of the State of Washington. Seller is duly qualified or
licensed to do business as a foreign corporation in each state of the United
States in which it is required to be so qualified or licensed, except in states
which the failure to qualify, in the aggregate, would not have a Material
Adverse Effect.

        4.2 Authorization. This Agreement and the Ancillary Agreements have
been, or upon their execution and delivery hereunder will have been, duly and
validly executed and delivered by Seller and constitute, or upon their execution
and delivery hereunder will constitute, valid and binding agreements of Seller
enforceable against Seller in accordance with their respective terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting creditors' rights generally or by general
equitable principles or the exercise of judicial discretion in accordance with
such principles. Seller has all requisite power and authority to execute, and
deliver this Agreement and, at the time of the Closing, will have all requisite
power and authority to execute and deliver the Ancillary Agreements and to carry
out the transactions contemplated herein and therein. All requisite corporate
action on the part of Seller has been taken to authorize the execution and
delivery of the Agreement and the Ancillary Agreements, subject only to the
approval of the Transaction and this Agreement by Seller's shareholders as
contemplated by Section 6.7. The affirmative vote of the holders of a majority
of the shares of common stock of Seller outstanding on the record date for the
Seller Shareholders' Meeting called pursuant to Section 6.7 (the "Required
Seller Shareholder Vote") is the only vote of the holders of any of Seller's
capital stock necessary under applicable Laws or Decrees to approve this
Agreement and the Ancillary Agreements and the transactions contemplated hereby
and thereby.

        4.3 No Conflicts; Consents. The execution and the delivery of this
Agreement and the Ancillary Agreements do not, and the consummation or
performance by Seller of the transactions contemplated herein and therein and
compliance with the provisions hereof and thereof will not, conflict with,
contravene, result in a breach of, constitute a default (with or without notice
or lapse of time, or both) under or violation of, or give any party a right to
terminate, accelerate, declare a default under or cancel any provision of, (a)
the Articles of Incorporation or Bylaws of Seller or any resolutions adopted by
the shareholders, board of directors or any committee of the board of directors
of Seller, (b) any Contract listed on Schedule 4.9(a) , except for a
non-material breach of, default under, or violation of any such Contract, or (c)
any Law or Decree applicable to Seller. Except for consents, authorizations,
filings, approvals and registrations required under any applicable Law or Decree
which, if not obtained or made, would not have a Material Adverse Effect and
would not prevent or materially alter or delay the Transaction, no consent of
any third party or any Governmental Entity is required to be obtained on the
part of Seller to permit the consummation of the transactions contemplated in
this Agreement and the Ancillary Agreements.

        4.4 Title to Assets; Sufficiency and Condition of Assets. Seller has
good and marketable title to all of the Assets, free and clear of all
Encumbrances except for Permitted Encumbrances. At the Closing, Seller will
sell, convey, assign, transfer and deliver to Purchaser good and marketable
title, and all Seller's right and interest in and to all of the Assets, free and
clear of all Encumbrances except for Permitted Encumbrances. The Assets will
collectively constitute, as of the Closing Date, all of the properties, rights,
interests and other tangible and intangible assets necessary to enable the
Purchaser to conduct the Business in the manner in which the Business has been
conducted by Seller and is currently proposed by Purchaser to be conducted. The
Transferred Inventory purchased by Purchaser is (a) free of any material defect
or deficiency and (b) in good, usable and currently marketable condition. All
inventory sold by Seller related to warranty, repair, support and code test
installation obligations to be assumed pursuant to Section 2.4 was, at the time
such inventory was sold by Seller, (a) free of any material defect or deficiency
and (b) in good, usable and currently marketable condition. All of the tangible
assets, equipment and fixed assets listed on Schedule 1.76 are structurally
sound, free of defects



                                       10


and deficiencies and in good condition and repair (ordinary wear and tear
excepted), and are adequate for the uses to which they are being put to use.

        4.5 Compliance with Laws. Seller is in compliance with all applicable
Laws or Decrees with respect to or affecting the Business, the Assets, or the
Assumed Liabilities, except for such failure to comply as which would not result
in a Material Adverse Effect. Seller is not subject to any order, writ, award,
judgment, injunction or decree issued by any Governmental Entity which could
impair the ability of Seller to consummate the transactions contemplated herein
or which could adversely affect Purchaser's conduct of the Business or its use
and enjoyment of the Assets or the Transferred Intellectual Property from and
after the Closing Date.

        4.6 SEC Reports; Seller Financial Statements. Seller has made available
to Purchaser or its counsel through EDGAR a true and complete copy of each
statement, report, registration statement (with the prospectus in the form filed
pursuant to Rule 424(b) of the Securities Act), definitive proxy statement, and
other filing filed with the SEC by Seller since January 1, 2000, and, prior to
the Closing, Seller will have made available to Purchaser or its counsel through
EDGAR true and complete copies of any additional documents filed with the SEC by
Seller prior to the Closing Date (collectively, the "Seller SEC Documents"). As
of their respective filing dates, none of the Seller SEC Documents contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements made therein, in light
of the circumstances in which they were made, not misleading, except to the
extent corrected by a subsequently filed Seller SEC Document prior to the date
hereof. The financial statements of Seller, including the notes thereto,
included in the Seller SEC Documents (the "Seller Financial Statements"),
complied as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto as of their respective dates, and have been prepared in
accordance with generally accepted accounting principles applied on a basis
consistent throughout the periods indicated and consistent with each other
(except as may be indicated in the notes thereto or, in the case of unaudited
statements included in Quarterly Reports on Form 10-Q, as permitted by Form 10-Q
of the SEC). The Seller Financial Statements fairly present the consolidated
financial condition and operating results of Seller and its subsidiaries at the
dates and during the periods indicated therein (subject, in the case of
unaudited statements, to normal, recurring year-end adjustments). There has been
no change in Seller's accounting policies except as described in the notes to
the Seller Financial Statements.

take any action described in this Section 4.7 or outside of its ordinary course

                                       16


               (a) Seller has not, to obtain or retain business, directly or
indirectly offered, paid or promised to pay, or authorized the payment of, any
money or other thing of value to (i) any Person who is an official, officer,
agent, employee or representative of any Governmental Entity or of any existing
or prospective customer (whether government owned or nongovernment owned), (ii)
any political party or official thereof, (iii) any candidate for political or
political party office, or (iv) any other Person while knowing or having reason
to believe that all or any portion of such money or thing of value would be
offered, given or promised, directly or indirectly, to any such official,
officer, agent, employee, representative, political party, political party
official, candidate or Person affiliated with such customer, political party or
official or political office.

               (b) The Seller has at all times been in compliance with all Laws
and Decrees relating to export control and trade embargoes. No product related
to the Business sold or service provided by Seller during the last three years
has been, directly or, to the Seller's Knowledge, indirectly, sold to or
performed on behalf of Afghanistan, Cuba, Iraq, Iran, Libya or North Korea.

               (c) The Seller has not violated the antiboycott prohibitions
contained in 50 U.S.C. Section 2401 et seq. or taken any action that can be
penalized under Section 999 of the Code. During the last three years, Seller has
not been a party to, been a beneficiary under or sold any product or performed
any service under any Contract under which a product has been sold, directly or,
to the Seller's Knowledge, indirectly, to customers in Bahrain, Iraq, Jordan,
Kuwait, Lebanon, Libya, Oman, Quatar, Saudi Arabia, Sudan, Syria, United Arab
Emirates or the Republic of Yemen.

        4.16 Ability to Pay Debts. Immediately after giving effect to the
consummation of the Transaction (a) Seller will be able to pay its debts as they
become due in the usual course of its business, (b) Seller will have assets
(calculated at fair value) that exceed its debts, and (c) taking into account
all pending and, to Seller's Knowledge, threatened litigation, no final judgment
against Seller in actions for money damages is reasonably anticipated to be
rendered at a time when, or in an amount such that, Seller will be unable to
satisfy any such judgment promptly in accordance with its terms as well as all
other obligations of Seller.

        4.17 Related Party Transactions. No Related Party has any direct or
indirect interest of any nature in any of the Assets or any assets relating to
the Business. Since January 1, 2001, no Related Party has entered into, or has
had any direct or indirect financial interest in, any Contract, transactions or
business dealing of any nature involving the Business. No Related Party is
competing, or has at any time since January 1, 2001 competed, directly or
indirectly, with the Business. To Seller's Knowledge, no event has occurred, and
no condition or circumstance exists, that might (with or without notice or lapse
of time) directly or indirectly give rise to or serve as a basis for any claim
or right in favor of any Related Party against or with respect to the Business.

        4.18 Accuracy of Material Facts; Copies of Materials. No representation,
warranty or covenant of Seller contained in this Agreement or in any
certificate, schedule or exhibit delivered pursuant to this Agreement contains
any untrue statement of a material fact or omits to state any material fact
necessary in order to make the statements contained herein and therein, taken as
a whole, not misleading in light of the circumstances under which such
statements were made. Seller has made available to Purchaser complete and
accurate copies of each Contract. Seller has delivered or, by Closing, will
deliver, accurate and complete copies of all Patents, Patent Applications
(including for those inventions for which Seller is in the course of preparing
or having applications prepared), and applications for or to register Trademark
or Copyrights, comprising the Transferred Intellectual Property, together with
all prosecution file history and other documentation with respect thereto that
is reasonably necessary for Purchaser to file, prosecute and maintain such
applications and registrations.

legal capacity and authority to enter into and perform its obligations under
this Agreement and the Ancillary Agreements. The execution and delivery of this

exercise of judicial discretion in accordance with such principles.

        5.3 No Conflict; Consents. The execution and the delivery of this
Agreement and the Ancillary Agreements do not, and the consummation or
performance by Purchaser of the transactions contemplated herein and therein and
compliance with the provisions hereof and thereof will not, conflict with,

or lapse of time, or both) under or violation of, or give any party any right to

Entity is required to be obtained on the part of Purchaser to permit the
consummation of the transactions contemplated in this Agreement or the Ancillary
Agreements.

        5.4 Litigation. There are no Proceedings or investigations, pending or
threatened against Purchaser before any Governmental Entity which questions or
challenges the validity of this Agreement or any of the Ancillary Agreements, or
any of the transactions contemplated herein or therein.

agreement of, or action taken by Purchaser.

        5.7 Accuracy of Material Facts. No representations, warranty or covenant
of Purchaser contained in this Agreement or in any certificate, schedule or

                         PRE-CLOSING COVENANTS OF SELLER

reasonable commercial efforts promptly to repair, restore or replace any assets
related to the Business that are destroyed or damaged.

               (b) Notwithstanding the foregoing, during the period on and from
the date of this Agreement through and including the Closing Date, Seller will
not without the prior written consent of Purchaser:

                      (i) mortgage, pledge, subject to a lien, or grant a
security interest in, or suffer to exist or otherwise encumber, any of the
Assets;

                      (ii) sell, dispose of or license any of the Assets to any
Person, except Inventory in the ordinary course of business, consistent with
past practices;

                      (iii) enter into any material contract relating to the
Business, or amend, terminate or waive any right under any Assumed Contract;

                      (iv) take any action or allow any action to be taken that
has a reasonable likelihood of diminishing in any material respect the value of
the Assets or interfere in any material respect with Purchaser's operation of
the Business after the Closing;

                      (v) declare or pay any bonus or declare or make any cash
incentive payment or similar payment to, or increase the amount of the wages,

past practices or pursuant to existing contractual arrangements existing as of
the date of this Agreement;

action to be taken that is reasonably likely to prejudice any future Tax

                      (vii) commence or settle any Proceeding relating to the
Business;



                                       19


                      (viii) fail to maintain the Tangible Assets in good
working condition and repair according to the standards it has maintained up to
the date of this Agreement, subject only to ordinary wear and tear; or

                      (ix) agree to do any of the things described in the
preceding clauses of this Section 6.1(b).

        6.2 Access to Information. Until the Closing, Seller will allow
Purchaser and its agents reasonable access upon reasonable notice and during
normal working hours to the Business Records and facilities relating to the
Assets, the Assumed Liabilities and the Business. Until the Closing, Seller
shall cause its accountants to cooperate with Purchaser and its agents in making
available all relevant financial information requested with respect to the
Assets, the Assumed Liabilities and the Business.

        6.3 Obtaining Necessary Consents and Addition of Purchaser as Party to
Certain Contracts. Seller will use its reasonable commercial efforts to obtain
the consents of any third parties or Governmental Entities necessary for (a) the
effective assignment to and assumption by Purchaser of the Assumed Contracts,
and (b) the consummation of the Transaction and the other transactions
contemplated hereby or by the Ancillary Agreements. All such consents shall be
in writing and executed counterparts thereof shall be delivered promptly to
Purchaser. To the extent that any Assumed Contract is not assignable without the
consent of another party, this Agreement shall not constitute an assignment or
an attempted assignment thereof, or thereunder, if such assignment or attempted
assignment would constitute a breach thereof until the necessary consents are
obtained. To the extent permitted by applicable law, in the event consents to
the assignment of the Assumed Contracts are not obtained by Seller as of the
Closing, such Assumed Contracts shall be held, as and from the Closing Date, by
Seller in trust for Purchaser, and the covenants and obligations thereunder
shall be performed by Purchaser in Seller's respective name and all benefits and
obligations existing thereunder shall be for Purchaser's account; provided,
however, that such performance by Purchaser shall be contingent on the passing
of all benefits of such Assumed Contracts to Purchaser. Seller shall not amend,
terminate or waive any right under any such Assumed Contract. Seller shall take
or cause to be taken such actions in its name or otherwise as Purchaser may
reasonably request so as to provide Purchaser with the benefits of the Assumed
Contracts and to effect collection of money or other consideration to become due
and payable under the Assumed Contracts, and Seller shall promptly pay over to
Purchaser all money or other consideration received by it in respect to all
Assumed Contracts.

        6.4 Satisfaction of Conditions Precedent. Seller will use its reasonable
commercial efforts to satisfy or cause to be satisfied all the conditions
precedent to the Closing hereunder, and to cause the transactions contemplated
herein to be consummated, and, without limiting the generality of the foregoing,
to obtain all consents and authorizations of third parties and to make all
filings with, and give all notices to, third parties, which may be necessary or
reasonably required on its part in order to effect the transactions contemplated
herein.

        6.5 No Solicitation.

               (a) During the period from and after the date hereof until the
earlier of the Closing Date or the termination of this Agreement in accordance
with Article XII, Seller shall not directly or indirectly, and shall not
authorize or permit any director, officer, employee, advisor (including, without
limitation, any investment bankers, attorneys or accountants) or agent of Seller
(each, a "Seller Representative") directly or indirectly to, (i) solicit,
initiate, intentionally encourage, facilitate or induce the making, submission
or announcement of any Acquisition Proposal, (ii) subject to the terms of the
immediately following sentence, participate in any negotiations regarding an
Acquisition Proposal, furnish to any Person any nonpublic information regarding
Seller to any Person in connection with or in



                                       20


response to an Acquisition Proposal, or take any other action that could
reasonably be expected to lead to an Acquisition Proposal, (iii) subject to the
terms of the immediately following sentence, approve, endorse or recommend any
Acquisition Proposal, or (iv) subject to the terms of the immediately following
sentence, enter into any letter of intent, preliminary agreement or similar
document contemplating or otherwise relating to any Acquisition. Notwithstanding
the foregoing, prior to the adoption of this Agreement by the Required Seller
Shareholder Vote, this Section 6.5(a) shall not prohibit Seller from furnishing
nonpublic information regarding Seller to, or entering into or facilitating or
encouraging discussions with or negotiations with, any Person in response to an
unsolicited proposal reasonably expected to result in a Superior Proposal
submitted to Seller by such Person (and not withdrawn); entering into any letter
of intent, agreement or similar document with any Person contemplating or
otherwise relating to a proposal reasonably expected to result in a Superior
Proposal submitted to Seller by such Person (and not withdrawn); or withdrawing
or modifying the recommendation of Seller's board of directors that Seller's
shareholders vote to approve this Agreement and the Transaction and endorsing or
recommending that Seller's shareholders vote to approve a proposal reasonably
expected to result in a Superior Proposal submitted to Seller by any Person (and
not withdrawn); if (1) neither Seller nor any Seller Representative shall have
violated any of the restrictions set forth in this Section 6.5, (2) the board of
directors of Seller concludes in good faith, after having taken into account the
advice of its outside legal counsel, that such action is required in order for
the board of directors of Seller to comply with its fiduciary obligations to
Seller's shareholders under applicable Laws or Decree, and Seller notifies
Purchaser of such determination of its board of directors and provides Purchaser
with a true and complete copy of the Acquisition Proposal, (3) at least three
(3) business days prior to furnishing any such nonpublic information to, or
entering into discussions with, such Person, Seller gives Purchaser written
notice of the identity of such Person and of Seller's intention to furnish
nonpublic information to, or enter into discussions with, such Person, and (4)
prior to furnishing any such nonpublic information to such Person, Seller enters
into a confidentiality and nondisclosure agreement with such Person on terms at
least as restrictive on such Person, taken as a whole, as the Confidentiality
Agreement, and Seller furnishes such nonpublic information to Purchaser (to the
extent such nonpublic information has not been previously furnished by Seller to
Purchaser).

               (b) Seller shall promptly advise Purchaser (and in any event
within 24 hours) orally and in writing of any Acquisition Proposal, any request
for information reasonably likely to lead to an Acquisition Proposal or any
request for nonpublic information relating to Seller (including the identity of
the Person making or submitting such Acquisition Proposal or request, and the
terms thereof) that is made or submitted by any Person prior to Closing.

               (c) Seller shall immediately cease and cause to be terminated any
existing discussions, activities or negotiations with any Person that relate to
any Acquisition Proposal.

        6.6 Proxy Statement. As promptly as practicable after the date of this
Agreement, Seller shall prepare and cause to be filed with the SEC the Proxy
Statement. Seller shall use all reasonable efforts to cause the Proxy Statement
to comply with the rules and regulations promulgated by the SEC and to respond
promptly to any comments of the SEC or its staff. Seller will use all reasonable
efforts to cause the Proxy Statement to be mailed to Seller's shareholders as
promptly as practicable. Purchaser shall promptly furnish to Seller all
information concerning Purchaser that may be required or reasonably requested in
connection with any action contemplated by this Agreement. If any event relating
to Seller occurs, or if Seller becomes aware of any information, that should be
disclosed in an amendment or supplement to the Proxy Statement, then Seller
shall promptly inform Purchaser thereof and shall file such amendment or
supplement with the SEC and, if appropriate, mail such amendment or supplement
to the shareholders of Seller. Notwithstanding the foregoing, prior to filing or
mailing the Proxy Statement (or any amendment or supplement thereto) or
responding to comments of the SEC with respect thereto, Seller (a) shall provide
Purchaser an opportunity to review and comment on all portions of such document



                                       21


or response that contain information about the Purchaser and (b) shall include
in such document or response all comments as reasonably proposed by Purchaser
which, in the reasonable judgment of Seller, are required or appropriate to
include in such document.

        6.7 Shareholders' Meeting.

               (a) Seller shall take all action necessary under all applicable
legal requirements to call, give notice of and hold a meeting of the holders of
Seller's common stock to vote on a proposal to approve this Agreement and the
Transaction (the "Seller Shareholders' Meeting"). The Seller Shareholders'
Meeting shall be held (on a date selected by Seller in consultation with
Purchaser) as promptly as practicable.

               (b) (i) The Proxy Statement shall include a statement to the
effect that the board of directors of Seller unanimously recommends that
Seller's shareholders vote to approve this Agreement and the Transaction at the
Seller Shareholders' Meeting (the unanimous recommendation of Seller's board of
directors that Seller's shareholders vote to adopt this Agreement being referred
to as the "Seller Board Recommendation"); and (ii) except pursuant to and in
compliance with Section 6.5(a), the Seller Board Recommendation shall not be
withdrawn or modified in a manner adverse to Purchaser, and no resolution by the
board of directors of Seller or any committee thereof to withdraw or modify the
Seller Board Recommendation in a manner adverse to Purchaser shall be adopted or
proposed.

        6.8 Advise of Changes. Seller will promptly notify Purchaser in writing
of any event occurring subsequent to the date of this Agreement that would
render any representation or warranty of Seller contained in this Agreement, if
made on or as of the date of that event or the Closing Date, untrue or
inaccurate to the extent that the condition set forth in Section 9.3(a) shall
not be satisfied. No such notification under this Section 6.8 shall be deemed to
amend or supplement the Seller Disclosure Schedule for the purpose of
determining the accuracy of any representation, warranty or statement in this
Agreement (for the purposes of Article XI or otherwise) unless the Closing
occurs, in which case such notification shall be deemed to amend the Seller
Disclosure Schedule solely as to the matter described therein.

        6.9 Transferred Inventory. For a period between ten (10) and five (5)
business days prior to the Closing Date, Purchaser shall be entitled to inspect
and perform quality assurance testing on the specific items of Transferred
Inventory to ensure that each such item of Transferred Inventory complies with
the specifications set forth on Schedule 6.9 (the "Quality Standards"). Subject
to the preceding sentence, the inspection and testing shall take place at such
times and locations as the parties may reasonably agree. Any specific item of
Transferred Inventory that does not meet such Quality Standards may, at the
Purchaser's sole option, be removed from the schedule of Transferred Inventory
and the Initial Purchase Price may be correspondingly reduced by the book value
of such item; provided, however, that Seller shall be allowed five (5) business
days to cure any non-compliance with the Quality Standards to the reasonable
satisfaction of Purchaser prior to any such reduction in the Initial Purchase
Price.

                                   ARTICLE VII
                       PRE-CLOSING COVENANTS OF PURCHASER

        7.1 Advise of Changes. Purchaser will promptly notify Seller in writing
of any event occurring subsequent to the date of this Agreement that would
render any representation or warranty of Purchaser contained in this Agreement,
if made on or as of the date of that event or the Closing Date, untrue or
inaccurate to the extent that the condition set forth in Section 9.2(a) shall
not be satisfied. No such notification under this Section 7.1 shall be deemed to
amend or supplement the Purchaser Disclosure Schedule for the purpose of
determining the accuracy of any representation, warranty or statement in this



                                       22


Agreement (for the purposes of Article XI or otherwise) unless the Closing
occurs, in which case such notification shall be deemed to amend the Purchaser
Disclosure Schedule solely as to the matters described therein.

        7.2 Satisfaction of Conditions Precedent. Purchaser will use its
reasonable commercial efforts to satisfy or cause to be satisfied all the
conditions precedent to the Closing hereunder, and to cause the transactions
contemplated herein to be consummated, and, without limiting the generality of
the foregoing, to obtain all consents and authorizations of third parties and to
make all filings with, and give all notices to, third parties which may be
necessary or reasonably required on its part in order to effect the transactions
contemplated herein.

                                  ARTICLE VIII
                                MUTUAL COVENANTS

        8.1 Confidentiality and Publicity. The parties acknowledge that the
Confidentiality Agreement is binding upon the parties hereto and in full force
and effect, except to the extent that the provisions hereof supersede provisions
to similar effect contained in the Confidentiality Agreement. The terms of the
Confidentiality Agreement (exclusive of such superseded provisions) are
incorporated in this Agreement by this reference.

        8.2 Regulatory Filings; Consents; Reasonable Efforts. Subject to the
terms and conditions of this Agreement, each of Seller and Purchaser shall use
its respective reasonable commercial efforts to (a) make all necessary filings
with respect to the Transaction and this Agreement under the Securities Act, the
Exchange Act and applicable blue sky or similar securities laws and obtain
required approvals and clearances with respect thereto and supply all additional
information requested in connection therewith, (b) make appropriate filings with
federal, state, provincial or local governmental bodies or applicable foreign
governmental agencies and obtain required approvals and clearances with respect
thereto and supply all additional information requested in connection therewith
and (c) take, or cause to be taken, all appropriate action, and do, or cause to
be done, all things necessary, proper or advisable to consummate and make
effective the transactions contemplated in this Agreement as promptly as
practicable.

        8.3 Employment Matters.

               (a) Key Employees. At or prior to the Closing Date, Purchaser
shall use its reasonable commercial efforts to enter into appropriate employment
documentation with each of the Key Employees, customary in scope and nature for
similarly situated employees of Purchaser. Seller agrees to use its reasonable
commercial efforts to retain the Key Employees, and shall notify Purchaser
promptly if, notwithstanding the foregoing, any Key Employee submits a
resignation to terminate employment or terminates employment prior to the
Closing Date.

               (b) Prospective New Purchaser Employees. At or prior to the
Closing Date, an offer of employment shall be made by Purchaser to each of the
Prospective New Purchaser Employees. Each such Prospective New Purchaser
Employee will be offered employment at a salary comparable to similarly situated
employees of Purchaser, as determined by Purchaser. Each Prospective New
Purchaser Employer who accepts the Purchaser's offer of employment (each, a
"Continuing Employee") shall be eligible to participate in the Purchaser's
benefit plans (such as medical benefits, bonuses, 401(k) and stock options) on
the same basis as other individuals beginning employment with Purchaser as a
newly-hired employee, provided that each Continuing Employee shall be given
credit for his or her period of continuous service with the Seller prior to the
Closing Date solely for the purpose of such individual's vacation accrual level
under Purchaser's standard policy. Seller agrees to use its reasonable
commercial efforts to retain the Prospective New Purchaser Employees, and shall
notify Purchaser promptly if,



                                       23


notwithstanding the foregoing, any Prospective New Purchaser Employee submits a
resignation to terminate employment or terminates employment prior to the
Closing Date. For each Prospective New Purchaser Employee who declines
Purchaser's offer of employment prior to the Closing Date (a "Declining
Employee"), Purchaser may make an offer of employment to any additional employee
of Seller not listed as a Prospective New Purchaser Employee, excluding those
employees who work in the Libra Business or for Libra Networks, (each, a
"Substitute Prospective New Purchaser Employee"). Purchaser's offer of
employment to each Substitute Prospective New Purchaser Employee shall be
subject to the consent of Seller, such consent not to be unreasonably withheld.
In the event that a Substitute Prospective New Purchaser Employee accepts
Purchaser's offer of employment, such Substitute Prospective New Purchaser
Employee's acceptance shall be deemed an acceptance of employment by a
Prospective New Purchaser Employee for the purposes of Section 9.3(l) and the
Declining Employee shall be excluded from any calculation required under Section
9.3(l).

        8.4 Further Assurances. Prior to and following the Closing, each party
to this Agreement agrees to cooperate fully with the other party and to execute
such further instruments, documents and agreements, and to give such further
written assurances, as may be reasonably requested by any other party to better
evidence and reflect the transactions described herein and the Ancillary
Agreements and contemplated herein and therein and to carry into effect the
intent and purposes of this Agreement.

        8.5 Non-Competition and Non-Solicitation. The Seller hereby covenants
and agrees that, until two (2) years from the Closing Date (the "Restricted
Period"), Seller shall not compete with Purchaser or its Affiliates in the
Business. The Seller hereby covenants and agrees that, until the end of the
Restricted Period, Seller will not, directly or indirectly, take any of the
following actions with respect to the Business: (a) solicit or divert any
business or clients or customers made known to it by Purchaser or its Affiliates
away from Purchaser or its Affiliates; (b) induce customers, clients, suppliers,
agents or other persons under contract or otherwise associated or doing business
with Purchaser or its Affiliates to reduce or alter any such association or
business with Purchaser or its Affiliates; and/or (c) knowingly solicit any
person in the employment of Purchaser or its Affiliates to (i) terminate such
employment and/or (ii) accept employment, or enter into any consulting
arrangement, with any person or entity other than Purchaser and/or its
controlled affiliates; provided, however, that nothing in this Section 8.5 shall
prohibit Seller from hiring employees of Purchaser who independently initiate
contact with, or solicit employment from, Seller.

        8.6 Taxes.

               (a) Seller shall be liable for and shall pay all Taxes (whether
assessed or unassessed) applicable to the Assets in each case attributable to
periods (or portions thereof) ending on or prior to the Closing Date. Purchaser
shall be liable for and shall pay all Taxes (whether assessed or unassessed)
applicable to the Assets in each case attributable to periods (or portions
thereof) beginning after the Closing Date. For purposes of this paragraph (a),
any period beginning before and ending after the Closing Date shall be treated
as two partial periods, one ending on the Closing Date and the other beginning
after the Closing Date except that Taxes (such as property Taxes) imposed on a
periodic basis shall be allocated on a daily basis.

               (b) Notwithstanding Section 8.6(a), any sales tax, use tax, gross
receipts tax, real property transfer or gains Tax, documentary stamp Tax or
similar Tax attributable to the sale or transfer of the Assets shall be paid by

Seller agrees to indemnify, defend and hold harmless Purchaser Indemnitees from,
against, and shall compensate and reimburse each Purchaser Indemnitee for and in
respect of any and all Losses asserted against, relating to, imposed upon or
incurred by any Purchaser Indemnitee by reason of, resulting from, based upon or
arising out of, whether directly or indirectly, (i) the breach, inaccuracy,
untruth or incompleteness of any representation or warranty of Seller contained
in or made pursuant to this Agreement, any Ancillary Agreement or any

               (b) Notwithstanding anything to the contrary contained in this
Agreement, no claim for Purchaser Indemnifiable Losses shall be made under this
Article XI: (i) unless Seller receives a Claim Notice during the Indemnification
Period, (ii) unless the aggregate of Purchaser Indemnifiable Losses shall exceed
$50,000 (at which point Seller shall become liable for the aggregate Losses, and
not just amounts in excess of $50,000), (iii) for any Losses to the extent that
the Purchaser Indemnitees have received payments in respect of claims made under
this Article XI in excess of $3,300,000 in the aggregate, (iv) to the extent the

incurred or sustained by any Purchaser Indemnitee or to which any of them
becomes subject to the extent such Losses arise from or were directly caused by
actions taken or failed to be taken by Purchaser or any of its Affiliates after
the Closing. The Purchaser Indemnitees' sole and exclusive remedy against Seller
for Losses shall be indemnification under this Article XI; provided, however,
that nothing contained in this Section 11.2(b) shall limit any remedy at law or
equity to which Purchaser may be entitled against Seller for fraud or
intentional misrepresentation.

        11.3 Indemnification by Purchaser.

               (a) Subject to the terms and conditions of this Article XI,
Purchaser agrees to indemnify, defend and hold harmless Seller Indemnitees from,
against, and shall compensate and reimburse each Seller Indemnitee for and in
respect of any and all Losses asserted against, relating to, imposed upon or
incurred by any Seller Indemnitee by reason of, resulting from, based upon,
arising out of, whether directly or indirectly, (i) the breach, inaccuracy,

Indemnitee for the purpose of enforcing any of its rights under this Article XI)
(collectively, "Seller Indemnifiable Losses"):

               (b) Notwithstanding anything to the contrary contained in this
Agreement, no claim for Seller Indemnifiable Losses shall be made under this
Article XI: (i) unless the aggregate of Seller



                                       29


Indemnifiable Losses shall exceed $50,000 (at which point Purchaser shall become
liable for the aggregate Losses, and not just amounts in excess of $50,000),
(ii) to the extent the Seller had a reasonable opportunity, but failed, in good
faith to mitigate the Losses, including but not limited to the failure to use
commercially reasonable efforts to recover under a policy of insurance or under
a contractual right of set-off or indemnity, (iii) for any Losses to the extent
that the Seller Indemnitees have received payments in respect of claims made
under this Article XI in excess of $3,300,000 in the aggregate, or (iv) with
respect to any Losses suffered, incurred or sustained by any Seller Indemnitee
or to which any of them becomes subject to the extent such Losses arise from or
were directly caused by actions taken or failed to be taken by Seller after the
Closing. The Seller Indemnitees' sole and exclusive remedy against Purchaser for
Losses shall be indemnification under this Article XI; provided, however, that
nothing contained in this Section 11.3(b) shall limit any remedy at law or
equity to which Seller may be entitled against Purchaser for fraud or
intentional misrepresentation

        11.4 Third-Party Claims. Should any claim be made, or suit or proceeding
(including, without limitation, a binding arbitration or an audit by any taxing
authority) be instituted against a Purchaser Indemnitee or Seller Indemnitee
which, if prosecuted successfully, would be a matter for which Purchaser
Indemnitee or Seller Indemnitee is entitled to indemnification under this
Agreement (a "Third Party Claim"), the obligations and liabilities of the
parties hereunder with respect to such Third Party Claim shall be subject to the
following terms and conditions:

               (a) The Person claiming indemnification under this Agreement (the
"Indemnified Person") shall give the indemnifying party (the "Indemnifying
Party") written notice of any such Third Party Claim promptly after receipt by
such Indemnified Person of notice thereof. Any delay in giving notice hereunder
which does not materially prejudice the Indemnifying Party shall not affect the
Indemnified Person's rights to indemnification hereunder. The Indemnifying Party
may, at its option, (i) undertake control of the defense thereof by counsel of
its own choosing, or (ii) decline to assume control of but participate in the
defense thereof. If the Indemnifying Party assumes control of the defense
thereof, (i) such Indemnifying Party will be precluded from disputing its
obligations under this Agreement to indemnify the Indemnified Party and (ii) the
Indemnified Person may participate in the defense through its own counsel at its
own expense. If the Indemnifying Party declines to control but elects to
participate in the defense thereof, the Indemnified Person may control the
defense and have its expenses promptly reimbursed by the Indemnifying Party.

               (b) Seller and Purchaser shall cooperate with each other in all
reasonable respects in connection with the defense of any Third Party Claim,
including making available records relating to such claim and furnishing
employees as may be reasonably necessary for the preparation of the defense of
any such Third Party Claim or for testimony as witness in any proceeding
relating to such claim.

               (c) Unless an Indemnifying Party has failed to fulfill its
obligations under this Article XI, no settlement by an Indemnified Person of a
Third Party Claim shall be made without the prior written consent by or on
behalf of the Indemnifying Party, which consent shall not be unreasonably
withheld or delayed. If the Indemnifying Party has assumed the defense of a
Third Party Claim as contemplated by Section 11.4(a), the Indemnifying Party may
settle such Third Party Claim so long as terms includes full release of all
claims against the Indemnified Person.

        11.5 Limitations.

               (a) The initial source for the Purchaser Indemnitees to collect
any Losses for which they may be entitled to indemnification under this Article
XI shall be to set off and retain such Losses against and from the Holdback
Amount. To the extent that the Losses for which the Purchaser Indemnitees may
seek indemnity under this Article XI are not set off against the Holdback Amount



                                       30


pursuant to the preceding sentence, the Purchaser Indemnitees shall have the
right to recover such remaining Losses from Seller in accordance with the rights
and remedies otherwise provided in this Agreement and/or available under
applicable law.

               (b) Nothing in this Agreement shall limit the Liability of any
Person to any other party for fraud or willful misconduct.

               (c) NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, IN NO
EVENT SHALL EITHER PARTY BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL,
COLLATERAL OR PUNITIVE DAMAGES IN CONNECTION WITH ANY CLAIMS, LOSSES, DAMAGES OR
INJURIES ARISING OUT OF THE CONDUCT OF THE PARTIES PURSUANT TO THIS AGREEMENT.

        11.6 Distribution of Holdback Amount. On the first business day
following the expiration of the Indemnification Period, the Holdback Amount,
less (a) any amounts which as of such date have been (i) applied to the
resolution of any matter referenced in any Claim Notice or (ii) set-off pursuant
to Schedule 2.6, less (b) any amounts which as of such date are subject to any
pending Claim Notice, shall be due and payable to Seller. On such date,
Purchaser shall deliver such portion of the Holdback Amount by wire transfer of
immediately available funds to an account designated in writing by Seller. Upon
resolution of any matter referenced in any Claim Notice, Purchaser shall deliver
the applicable remaining portion of the Holdback Amount (reduced by any amounts
which have been applied to the resolution of any matter referenced in any Claim
Notice), if any, to Seller. No interest shall be paid or accrue on the Holdback
Amount or any portion thereof payable to Seller pursuant to this Section 11.6.

performed by such party at or prior to the Closing);

               (c) by either Purchaser or Seller if a court of competent

held and completed and Seller's shareholders shall have taken a final vote on a
proposal to adopt this Agreement, and (ii) this Agreement shall not have been
adopted at such meeting by the Required Seller Shareholder Vote (and shall not
have been adopted at any adjournment or postponement thereof); provided,
however, that a party shall not be permitted to terminate this Agreement
pursuant to this Section 12.1(d) if the failure to obtain such shareholder
approval is attributable to a failure on the part of such party to perform any
material obligation required to be performed by such party at or prior to the
Closing;



                                       31

terminate this Agreement pursuant to this Section 12.1(f) if such inaccuracy or
breach shall not have been cured within thirty (30) days after receipt by Seller
of written notice of such inaccuracy or breach; or

               (g) by Seller if (i) any of Purchaser's representations and
warranties contained in this Agreement shall be inaccurate as of the date of

would not be satisfied, or (ii) if any of Purchaser's covenants contained in
this Agreement shall have been breached such that the condition set forth in
Section 9.2(b) would not be satisfied; provided, however, that Seller may only
terminate this Agreement pursuant to this Section 12.1(g) if such inaccuracy or
breach shall not have been cured within thirty (30) days after receipt by
Purchaser of written notice of such inaccuracy or breach.

        12.2 Effect of Termination. In the event of the termination of this
Agreement as provided in Section 12.1, this Agreement shall be of no further

and Article XIII shall survive the termination of this Agreement and shall
remain in full force and effect, and (b) the termination of this Agreement shall

                                  ARTICLE XIII
                                     GENERAL



                                       32


        13.1 Governing Law and Jurisdiction. The parties agree that this
Agreement, and any disputes arising under this Agreement, will be governed by
and construed in accordance with the laws of the state of Washington or, in the
case of disputes involving Intellectual Property covered by this Agreement,
applicable U.S. law, state law or other law governing such Intellectual
Property, without giving effect to any conflict of laws principle to the
contrary. Subject to Section 13.2, the parties agree that venue for any dispute
arising under this Agreement will lie exclusively in the state or federal courts
located in Cook County, Illinois, and the parties irrevocably waive any right to
raise forum non conveniens or any other argument that Illinois is not the proper
venue. Subject to Section 13.2, the parties irrevocably consent to personal
jurisdiction in the state and federal courts of the state of Illinois.

        13.2 Amicable Resolution. The parties mutually desire that friendly
collaboration will develop between themselves. Accordingly, they shall try to
resolve in a friendly manner all disagreements and misunderstandings connected
with the respective rights and obligations under this Agreement. To the extent
that any misunderstanding or dispute which arises after the Closing Date cannot
be resolved in a friendly manner (other than misunderstandings or disputes
involving Intellectual Property covered by this Agreement), the dispute will be
mediated by a mutually-acceptable mediator to be chosen by the parties within 45
days after written notice by one party to the other demanding mediation. Neither
party may unreasonably withhold consent to the selection of the mediator;
however, by mutual agreement, the parties may postpone mediation until each has
completed specified but limited discovery with respect to a dispute. The parties
may also agree to utilize some other form of alternative dispute resolution in
lieu of mediation, including by way of example and without limitation, neutral
fact-finding or a mini-trial. Any dispute that the parties cannot resolve
through negotiation, mediation or other form of alternative dispute resolution
within six (6) months of the date of the initial demand for it by one of the
parties may then be submitted to the courts for resolution pursuant to Section
13.1. The use of any alternative dispute resolution procedures will not be
construed under the doctrine of laches, estoppel or waiver to adversely affect
the rights of either party. Nothing in this Section 13.2 shall prevent either
party from resorting to judicial proceedings if (a) good faith efforts to
resolve the dispute under these procedures have been unsuccessful, or (b)
interim relief from a court is necessary to prevent serious and irreparable
injury to one party or the other.

        13.3 Assignment; Binding upon Successors and Assigns. None of the
parties hereto may assign any of its rights or obligations hereunder without the
prior written consent of the other party, which consent shall not be
unreasonably withheld. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective permitted successors and
assigns.

        13.4 Severability. If any provision of this Agreement, or the
application thereof, shall for any reason and to any extent be held to be
invalid or unenforceable, the remainder of this Agreement and the application of
such provision to other persons or circumstances shall be interpreted so as best
to reasonably effect the intent of the parties hereto. The parties further agree
to replace such invalid or unenforceable provision of this Agreement with a
valid and enforceable provision which will achieve, to the extent possible, the
economic, business and other purposes of the invalid or unenforceable provision.

        13.5 Entire Agreement. This Agreement, the Ancillary Documents, and
each exhibit, schedule, certificate appended hereto and thereto or referenced
herein or therein, and the Confidentiality Agreement constitute the entire
understanding and agreement of the parties hereto with respect to the subject
matter hereof and thereof and supersede all prior and contemporaneous agreements
or understandings, inducements or conditions, express or implied, written or
oral, between the parties with respect hereto and thereto.



                                       33


        13.6 Counterparts. This Agreement may be executed in any number of
counterparts, including counterparts transmitted by facsimile, each of which
shall constitute an original and all of which together shall constitute one and
the same instrument.

        13.7 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party shall be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy shall not preclude the exercise of any other.

        13.8 Amendment and Waivers. Any term or provision of this Agreement may
be amended, and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof for default in payment of any amount due
hereunder or default in the performance hereof shall not be deemed to constitute
a waiver of any other default or any succeeding breach or default.

        13.9 Notices. All notices and other communications hereunder will be in
writing and will be deemed given (a) upon receipt if delivered personally (or if
mailed by registered or certified mail), (b) the day after dispatch if sent by
overnight courier, (c) upon dispatch if transmitted by telecopier or other means
of facsimile transmission (and confirmed by a copy delivered in accordance with
clause (a) or (b)), properly addressed to the parties at the following
